Slip conditions : velocity of the wall
Ver: 0
 

DESCRIPTION

This menu allows to set the velocity of the wall when considering a slipping boundary conditions.

The velocity of the wall is defined by a combination of a translation and a rotation.

  OPTIONS
For 2D problems :
 
-1
 Upper level menu
   1 
 Modify rotation center
Note here that the rotation axis is oriented from the origin of the coordinate system towards positive Z coordinates.
2
 Modify  angular velocity
The angular velocity is specified with respect to the Z axis
3
 Modify  translation velocity
The two components of the translation velocity in a cartesian reference frame are specified here

For 3D problems :
 
-1
 Upper level menu
   1 
 Modify  1st point of the axis
Note here that the rotation axis will be oriented from the first to the second point, and that the angular velocity will be defined with respect to this orientation
2
 Modify  2nd point of the axis
3
 Modify  angular velocity
The angular velocity is specified with respect to the oriented rotation axis
4
 Modify  translation velocity
The three components of the translation velocity in a cartesian reference frame are specified here
